      Some closer examination of the PL310 TRM reveals that there's no need to poll for completion of maintenance operations if we only use atomic ops.
      Since there's no particular need for us to use the background ops, just rewrite everything to use the atomic ops and get rid of the polling.
      This should also avoid the need for any costly locking in SMP setups.
